PIN-TONGUE JOINT.

SPECIFICATION forming part Of Letters Patent NO. 767,895, dated August 16, 1904:-

Application filed February 23, 1904. Serial No. 19 L963. (N0 model.)

To all whom it may concern:

Be it known that I, CHESTER W. KELLEY, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful Improvement in Pin- Tongue Joints, of which the following is a specification.

The nature of my invention consists in the improved construction of the post to which the tongue is jointed and in the combination of the pin-tongue therewith.

In the accompanying drawings, Figure 1 represents the side view of a brooch-pin provided with my improved pin-tongue joint. Fig. 2 represents a back view of the same. Fig. 3 represents an end view. Fig. 4L represents a side view of the joint-pdst. Fig. 5 represents an end view of the same. Fig. 6 represents a section taken in the line 6 6 of Fig. 5. Fig. 7 represents a side view of the tongue. Fig. 8 represents an enlarged detail section taken in the line 8 8 of Fig. 2, showing the construction of the joint.

In the drawings, A represents the plate of the hrooch-pin; B. the pivot-post; C, the pintongue, and D the engaging hook for the pintongue. The post B is provided with a central bore a and with a contracted neck 6 and also provided at its outer end with the limiting-shoulder c, which serves to prevent further swinging movement of the pin-tongue D. The shank (Z of the pin tongue C is turned at right angles to the pin and provided with a circumferential groove 6, and upon the inwhich serves to hold the pin-tongue in its engaged position, is provided at its end with the knob g,which serves to prevent the accidental disengagement of the pin tongue from the hook.

I claim as my invention 1. In a pin-tongue joint, the combination of the pin-tongue having a deflected shank provided with a holding-groove, with the hollow post having a contracted neck, and having its bore constricted at the contracted neck into the holding groove of the shank of the pintongue, substantially as described.

2. In a pin-tongue joint, the combination of the pin-tongue having a deflected shank provided with a holding-groove, with the hollow post having a contracted neck and a limitingshoulder for the lateral traverse of the pintongue, and having its bore constricted at the contracted neck into the holding-groove of the shank of the pin-tongue, substantially as described.

CHESTER WV. KELLEY.
